Reef Calcium Tailored Aquatics uses only the highest quality ingredients to ensure top quality products. Tailored Aquatics Reef Calcium is extremely concentrated. Calcium levels in a reef tank should be between 420ppm - 450ppm.Tailored Aquatics Reef Calcium Plus has the ability to raise calcium levels fast. But use caution not to raise calcium more than 40 ppm per day. Reef Calcium plus provides bio-available calcium for lush growth of purple, pink and green calcareous algae, snails, and clams. Reef Calcium Plus will not affect the pH or alkalinity of your aquarium and should be used in conjunction with Reef dKH Plus for alkalinity and ph maintenance. Phosphate and nitrate free! Reef Calcium Plus alone can provide all the calcium your reef will need, but for maximum results, use Tailored Aquatics Reef Kalk/w Kalk booster first, then supplement calcium level with this product as needed.

Concentrated at nearly 200,000 ppm Reef Calcium Plus is super concentrated blend of Calcium, Magnesium, Strontium with Nitrate Destroyer. Nitrate Destroyer's Benefits are providing a great source of metabolic energy which indirectly and directly give corals a source of energy as while reducing nitrates at the same time. Contains no sugars, yeast or glucose! Please Note that due to its high concentration, if product has been stored in cold temperatures some precipitate may occur. This does not effect the performance of the product.

I found this to be a really good product for a set-up like mine, large water volumn with a slightly moderate amount of corals. It's easy to use and to slowly increase your dosing until you get the Cal level you want
